2017-06-12Accept IPv6 address %suffixes when parsingRaimo Niskanen
This only implements decimal suffixes, and furthermore only with a leading "0". A complete implementation would probably allow one and probably two digit suffixes without. But what primarily is missing is translating interface names to and from interface indexes. This also only implements the parsing, and uses the FreeBSD trick of squeezing in the Scope Id in the second 16-bit word of the fe80::/64 or ff02:/64 address prefix. But inet_drv is not prepared to handle this word, so it might only work on FreeBSD, not being supported even there... So inet_drv needs to handle this too.

2017-06-07Adjust inet:ntoa/1 to RFC5952, but not deeperRaimo Niskanen
There are a multitude of RFC:s that point to each other and some of them suggest different addresses with IPv4 suffixes. Use the IPv4 suffix text representation only for the old well known ::a.b.c.d and ::ffff:a.b.c.d prefixes. The others seems to be moving targets.

2017-06-07erts: Fix sendfile closeduring scenario on sunosLukas Larsson
On Solaris, giving a too long sfv_len results in an EINVAL error, but data is still transmitted and len is correctly. So we translate this to a success with that amount of data sent. This may hide some other errors that causes EINVAL, but it is the best we can do for now.

2017-05-22kernel: Skip ipv6 tcs when cpiv6 is disabledLukas Larsson
For some reason doing a gen_udp:open(0, [inet6,{ipv6_v6only,true}]) works on some systems where ipv6 is disabled. So instead we explicitly require the localhost ip to do the test at which seems to work better. ipv6 was disabled in sysctl using the line net.ipv6.conf.all.disable_ipv6=1 when this behaviour was found.

2017-05-18kernel: Add error_logger:limit_term/1Hans Bolinder
Calling error_logger:limit_term/1 before sending terms as events to the error_logger can be used for limiting the size of the messages. Doing so will not change the output, but potentially save memory. The Kernel variable error_logger_format_depth is used when limiting the size of terms.
2017-05-17Add persistence to history of the non-legacy shellFred Hebert
This patch adds a mechanism by which shell history gets stored persistently on disk and gets loaded whenever a new shell session begins. The log files are added to the user's cache directory, with multiple files in it, although the location is configurable. All Erlang instances on a given host will share the same log file. There are two hook points in group.erl that are used: when instantiating the buffer, where we fetch from disk, and when adding a line to the buffer (gets stored). This allows all shell instances to use the same base set of lines when loaded, but to keep their history separate after the fact. As lines are added as you go, a new shell session (with ^G -> s -> c) will have access to previous sessions' lines. The implementation makes use of the disk_log library with a rotating log in order to store data, and allow automated repairs. By default, the feature is disabled and must be turned on through OTP environment variable part of the kernel application. The options include: | Option | Accepted values | Default | Description | | ------------------------ | ----------------- |---------- | -------------------- | | shell_history | enabled, disabled | disabled | turn feature on/off | | shell_history_path | any string | user cache| where to put files | | shell_history_file_bytes | 51200..N bytes | 512kb | max data size (>50kb)| | shell_history_drop | ["q().", ...] | [] | blacklisted lines | A version header is added to the disk_log configuration, allowing changes in the storage format to be enacted in the future (i.e. adding segmentation by node name in the same file, or encoding) without conflict. Log rotation is used with multiple log files to ensure proper enforcement of resizing without too much data loss. Because disk_log does not allow to just flush bits of content on rewrite (it truncates any full file), we instead use a wrap log and try to divide the configured size into up to 10 log files so that every time we rotate a log, we lose only 10% of the data. This remains true for corrupted files that cannot fully be repaired. This many-logs-based approach in turn forces the use of a minimal log size for the `shell_history_file_bytes` configuration, since it has to be divided by 10. The shell history is not loaded for the `user` process which, despite running the group.erl module, does not actually require history as it mostly just forwards IO protocol information.
2017-05-17add option 'quiet' to disk_logFred Hebert
This option allows to suppress output of info_msgs to error_logger when recoverable errors are encountered in disk_log by setting the value to 'true'. Defaults to 'false', the backwards compatible behaviour.
